This 1 inchspacer fits between the upper and lower intake on Edelbrock performer and performer RPM fuel injection manifolds . Has the effect of making the runners longer for more torque. Also raises the upper intake for more valve cover clearance. The best part is it helps insulate the upper manifold from heat that really hurts the power on 5.0 Mustangs, and Thunderbirds. CNC machined from a Automotive approved heat resistant. high tech composite material. This material is not cheap but much better quality.

Note many buyers have asked for no EGR hole since it hurts power so much. So the updated version does not have one. Easy to drill but hard to plug.

Includes 1 inch SPACER

Studs, washers, and nuts as pictured

HDPE Reuseable gaskets
